U.S. and 5 Allies Warn China Over Panama Ship Detentions

The Panama ships China confrontation has escalated from a port concession fight into a full multinational standoff over maritime sovereignty in the Western Hemisphere.

The escalating dispute over Panama ships and China reached a new threshold on Tuesday when the United States and five allied nations issued a joint statement condemning Beijing’s targeted detention of Panama-flagged vessels. The Rio Times, the Latin American financial news outlet, reports that the declaration marks the first formal multilateral response to months of Chinese port-state crackdowns following Panama’s decision to revoke CK Hutchison’s canal port concessions.

Secretary of State Marco Rubio released the statement alongside Bolivia, Costa Rica, Guyana, Paraguay, and Trinidad and Tobago. The six nations warned that recent actions affecting Panama-flagged vessels in Chinese ports represent an attempt to politicize maritime trade and infringe on hemispheric sovereignty.

What the Panama Ships China Dispute Actually Looks Like

The numbers tell the story. In March 2026, Chinese ports detained 91 Panama-flagged vessels out of 123 total detentions under the Tokyo MOU inspection regime. That represents roughly 74% of all ships detained in the Asia-Pacific region, far above any historical precedent.

In January, the figure was 25 Panamanian ships; in February, it dropped to 19 before surging in March.

The detentions are formally tied to safety deficiencies such as fire-control systems, pollution-prevention equipment, and crew documentation. But the timing aligns precisely with Panama’s Supreme Court ruling in January that invalidated CK Hutchison’s concession to operate the Balboa and Cristobal terminals at each end of the Panama Canal.

US Federal Maritime Commission chair Laura DiBella said the detentions were carried out under informal directives and appeared intended to punish Panama. She warned that because Panama-flagged ships carry a meaningful share of US containerized trade, the campaign could have significant commercial consequences for American shipping.

Why These Six Countries Signed

The coalition is notable for its composition. Bolivia, Costa Rica, Guyana, Paraguay, and Trinidad and Tobago are all governments that have aligned with Washington’s hemispheric security agenda in recent months. Several have signed bilateral agreements with the United States that include explicit provisions on Chinese infrastructure access.

Absent from the statement are the region’s largest economies. Brazil, Mexico, Colombia, Argentina, and Chile did not sign, reflecting the political complexity of publicly confronting Beijing when Chinese trade and investment remain critical to their economies. The coalition is therefore a group of smaller nations willing to take a public position that the heavyweights will not.

Rubio said separately that the sovereignty of the hemisphere is non-negotiable and that the United States is deeply concerned by China’s economic coercion after the Balboa and Cristobal terminals decision.

Beijing Fires Back

China’s foreign ministry responded swiftly on Wednesday. Spokesman Lin Jian called the joint statement a smear and accused the United States of being the one politicizing and over-securitizing the port issue. Beijing has maintained throughout the dispute that the Panamanian court ruling was made under US pressure and that Washington, not Beijing, is the party attempting to control the canal.

The Chinese government has also summoned representatives from Maersk and MSC to Beijing for high-level discussions after the two shipping giants assumed interim management of the Balboa and Cristobal terminals. State-owned COSCO Shipping suspended container services at Balboa in March, while CK Hutchison has filed international arbitration seeking over two billion dollars in damages from Panama.

What This Means for Global Shipping

Panama maintains the world’s second-largest ship registry after Liberia, with over 8,800 vessels. A sustained campaign of targeted detentions raises costs for every shipowner using the Panamanian flag and could push registrations toward other registries, undermining a pillar of Panama’s economy.

The dispute also comes at a moment when the Strait of Hormuz crisis has already disrupted global shipping routes, pushing more traffic toward the Panama Canal and raising transit premiums. Analysts have noted that the convergence of two maritime chokepoint crises magnifies the risk for supply chains that depend on either route.

For Latin America, the joint statement signals a hardening of the US-led alignment on infrastructure sovereignty, even as the region’s largest nations stay on the sidelines. The question now is whether the diplomatic escalation forces Beijing to recalibrate or whether it deepens the cycle of economic retaliation that has already turned port-state control into a geopolitical weapon.
